DOW DOWSIL FS DB - 110N is a 14% active siloxane defoamer emulsion, expertly designed for industrial water treatment and high - foam surfactant systems. Presenting as a low - viscosity milky liquid with a viscosity of 300 - 500 mPa·s, it showcases remarkable stability. Operating within a pH range of 2 - 12 and at temperatures up to 80°C, it has a dynamic surface tension as low as 24 dyn/cm. This allows it to rapidly eliminate micron - level foam, providing over 6 hours of suppression. It's especially effective in high - salinity wastewater treatment, reducing the use of mineral oil defoamers by 15%, while also enhancing efficiency in detergent production and food processing.
Swift Defoaming Performance: Its nano siloxane particles are engineered to break down foam within just 5 minutes. This makes it highly suitable for high - shear cleaning lines where quick foam elimination is crucial.
Exceptional Condition Resistance: DOW DOWSIL FS DB - 110N can endure extreme conditions. It resists the wide pH spectrum from 2 - 12, high salinity environments, and temperatures of up to 80°C without any degradation in its performance.
Extended Shelf Life: With a 360 - day stability period at temperatures between 4 - 50°C, it ensures long - term usability. Even when diluted at a 1:10 ratio, it remains homogeneous, maintaining its effectiveness.
Chemical Wastewater Treatment: In high - COD aeration tanks, it effectively controls foam when dosed at 0.2% - 0.8%. This helps in optimizing the wastewater treatment process and improving the quality of treated water.
Food Processing: Being FDA - compliant, it is suitable for use in fermenters and cleaning lines within food processing facilities. The maximum allowable dosage, as per GB 2760, is 0.3g/kg, ensuring food safety while managing foam.
Industrial Detergents: In high - surfactant systems used in industrial detergents, it minimizes foam, enabling efficient filling of detergent products. This leads to better product quality and production efficiency.
